I Have a Pallium. We have Pallia.

Pope Francis celebrated Mass in St. Peter’s Basilica on June 29, the Solemnity of Saints Peter and Paul, and blessed the pallia that will be conferred on metropolitan archbishops by pontifical representatives.
As is customary, a delegation from the Ecumenical Patriarchate of Constantinople, led this year by Metropolitan Methodios Tournas of Boston, attended the Mass in honor of the patrons of Rome.

Blessed the what?

The pallium (derived from the Roman pallium or palla, a woolen cloak,  pl.: pallia) is an ecclesiastical vestment in the Catholic Church, originally peculiar to the Pope, but for many centuries bestowed by him on metropolitans and primates as a symbol of the jurisdiction delegated to them by the Holy See. In that context it has remained connected to the Papacy.
The pallium, in its present Western form, is a narrow band, "three fingers broad", woven of white lamb's wool from sheep raised by Trappistt monks, with a loop in the centre resting on the shoulders over the chasuble and two dependent lappets, before and behind; so that when seen from front or back the ornament resembles the letter Y. It is decorated with six black crosses, one on each tail and four on the loop, is doubled on the left shoulder, and sometimes is garnished, back and front, with three jeweled gold pins. The two latter characteristics seem to be survivals of the time when the Roman pallium was a simple scarf doubled and pinned on the left shoulder.

The Papal Pallium

Humeral Veil

You may have noticed that on Corpus Christi, Father held the monstrance with his hands wrapped in a scarf like thing. That's called a humeral veil. It is usually white or gold, but may also be the liturgical color of the season.

Not Father Uriel. This is retired Cardinal Godfried Daniels of Belgium.

The humeral veil is not to be confused with the vimpa, which is narrower and worn by altar boys when the Bishop is present. The use it to cover their hands when the Bishop hands them the mitre or crosier.

The hat is the mitre; the staff is the crozier.
